Unformatted text preview: Inc., New York, NY, 1951, pg. 35, article 20. Analysis Type(s): Static Analysis (ANTYPE = 0) Element Type(s): Linear Layered Structural Shell Elements (SHELL99) Input Listing: vm78.dat Test Case A cantilever beam of length L, height h, and width w is bent by a force F applied at the free end. Modeling the beam using SHELL99 shell elements having four layers of identical material properties and thickness, determine the shear stress distribution through the beam thickness and the maximum Tsai-Wu failure criterion. The normal and shear failure stresses are σxf and σxyf respectively. Figure 78.1 Cantilever Beam Problem Sketch Material Properties E = 30 x 106 psi υ=0 σxf = 25000 psi σxyf = 500 psi Geometric Properties L = 10.0 in w = 1.0 in h = 2.0 in Loading F1 = 10000 lb Analysis Assumptions and Modeling Notes Poisson's ratio is set to zero to model the narrow beam assumption. The failure stresses are input in the nonlinear material property table (TB commands). Compression values are allowed to default to negative tension values and arbitrary values are assigned to failure stresses in the Y and Z direction...
